Where to Buy or Rent

The B218 achieves the ultimate in subwoofer performance for the most prestigious Blackline 3 applications – delivering very high output levels and superb transient performance with minimal distortion. With an operating range of 35-150Hz, it houses dual long-excursion 18” (460mm)/4” (100mm) voice coil drivers with water-resistant cones and triple roll surrounds. Each driver is rated to handle 1000 watts AES, and has a magnet structure and suspension engineered for maximum linear excursion.

Features

  • Dual-driver, direct-radiator subwoofer
  • Long-excursion 18” (460mm) drivers with 4” (100mm) voice coils
  • Water resistant cones
  • Birch-ply enclosure construction
  • Large ports for reduced air noise
  • Perforated steel grille

Applications

  • Live music clubs
  • Music bars
  • Nightclubs
  • Premium KTV

The enclosure of the B218 is constructed from multi-laminate birch ply and coated with a textured black finish. Eight reflex ports provide a large frontal area to reduce turbulent air noise, and a perforated steel grille protects the driver from damage with minimal obstruction of airflow.

When used with a Blackline 3 FX12 or FX15 coaxial system, crossover and EQ functions can be performed by the Martin Audio DX0.4 or DX0.6 Loudspeaker Management System.
